At present, the mainstream PC brick making machines circulating in the market generally adopt an integrated design scheme of electromechanical and hydraulic systems. The overall structure of the machine is scientific and orderly, mainly including six core components: basic frame, layered fabric system, hydraulic pressure unit, vibration auxiliary mechanism, automatic conveying module, and intelligent electronic control console. The interlocking logic of the program is set for each operating component of the equipment, which can autonomously match the production rhythm, effectively reduce the frequency of manual intervention, minimize the differences in finished product specifications caused by human operation deviations, and ensure the consistency of products in mass production.
        The equipment rack adopts a thickened steel welded frame structure with good structural stability, which can adapt to continuous working conditions of long-term pressure and vibration, and is not prone to structural deformation problems. The mold adopts a combined detachable design, and the staff can quickly change the mold frames of different specifications according to the production order requirements, and flexibly produce various types of concrete products such as sidewalk bricks, tactile paving bricks, curb stones, grass planting bricks, etc. The layered fabric system independently sets up a bottom material bin and a fabric bin. The two types of production materials are stored separately and transported independently for unloading, which can evenly ensure the strength of the brick bottom structure and the color and texture of the surface layer, and smoothly control the weight and specification errors of individual finished products. The hydraulic system is equipped with a stable pressure oil circuit design, with constant pressure parameters during the molding cycle. After the molding is completed, the mold is released at a constant speed, which can effectively reduce the probability of brick cracking, corner defects, and uneven molding defects.
        The daily standardized operation and maintenance of PC brick making machines are mainly divided into three core stages: pre shift inspection, production inspection, and post shutdown maintenance. During pre shift homework, the staff need to check the hydraulic oil level of the equipment, the vibration motor circuit, and the fastening status of the mold bolts one by one, clean up the residual clumped raw materials inside the silo, and avoid problems such as fabric blockage and uneven feeding during the production process. During the production and operation of the equipment, it is necessary to regularly observe the forming pressure, fabric uniformity, and equipment operating status, record basic parameters such as oil pressure and operating noise, and promptly stop the machine for troubleshooting when abnormal parameters or equipment noise are found, in order to avoid equipment failures caused by minor problems. After the daily production operation is completed, it is necessary to clean the surface of the whole machine and the raw material residue in the material bin and mold multiple times. Lubricating grease should be added to the moving parts such as the equipment slide rail and guide column. At the same time, according to the equipment maintenance cycle, hydraulic filter elements, seals and other easily consumable parts should be replaced regularly.
        A standardized equipment operation and maintenance ledger can be established for small and medium-sized building materials production lines, which records in detail the replacement cycle of core components, daily fault handling, equipment maintenance records, and other information. Based on the cumulative operating time of the equipment, quarterly and annual in-depth maintenance work can be reasonably planned. Normalizing the implementation of standardized equipment maintenance work can effectively extend the service life of the entire machine, stabilize the output efficiency of single shift products, reduce the frequency of sudden equipment shutdowns for maintenance, minimize the impact of production interruptions on production progress, and adapt to the continuous and normalized production operation needs of building materials enterprises.
